Change MacOS Monterey Login Screen Wallpaper

In this article, we are going to discuss the macOS Monterey login wallpaper and the process to change it. So let’s get started.

A pink and purple background appears on the login screen, lock screen, and Desktop on macOS Monterey by default. Apparently, both the Login screen and Lock screen show the same background as the desktop. Yes, the login and lock screen is different.

You shouldn’t confuse the login screen with the lock screen as both are different. The login screen appears when you startup/boot or log out of a user account whereas the lock screen appears when you lock your Mac. While you can’t change the lock screen in Monterey on Mac, which boasts the same background image as your desktop. However, there is a way you can use to change the login screen on macOS Monterey.

There are two ways we will be discussing in this article. The first trick involves using a third-party app, ‘Deeper’ by Titanium Software to change the background image of the login window. It can get the task done in a few clicks and without any complicated steps. And the second one is by using the UUID number. So, let’s discuss them one by one.
